* fix(plugins): stop core updates from resurrecting uninstalled built-in plugins

Built-in plugins (e.g. web-ui-info, starlark-apps) are committed into the
repo under plugin-repos/. When a user uninstalls one, a subsequent core
`git pull` update restores the committed files, so the plugin reappears on
every update. The update endpoint stashes the deletion and never pops it,
and `git pull` faithfully restores any committed file whose deletion was
never committed — so excluding plugin-repos/ from the stash can't fix this
(it would only make `git pull --rebase` fail on a dirty tree).

Add a persistent uninstall registry (config/uninstalled_plugins.json,
gitignored) that survives restarts, unlike the existing in-memory tombstone:

- Uninstall records the plugin id; install clears it.
- purge_uninstalled_plugins() re-removes any recorded plugin whose directory
  reappears on disk; called after a successful git-pull update and at web
  startup (covers manual `git pull` on the Pi too).
- The state reconciler also refuses to auto-repair a persistently
  uninstalled plugin.

Wires up mark_recently_uninstalled in the uninstall flow (previously only
referenced by tests) via the new persistent record.

Adds regression tests covering record/forget/purge lifecycle, persistence
across manager instances, and corrupt-registry tolerance.

* fix(plugins): validate uninstall-registry ids and lock registry writes

Address review feedback on the persistent uninstall registry:

- Critical: validate plugin ids on read/record and add a containment guard
  in purge_uninstalled_plugins. A corrupt or hand-edited registry entry of
  "" resolves to the plugins root, so purge could have deleted every plugin;
  traversal ids ("..", "../x") could target paths outside the root. Invalid
  ids are now dropped on read, refused on record, and never removed unless
  the path is a direct child of the plugins directory.
- Major: guard record/forget read-modify-write with a lock so concurrent
  install/uninstall requests can't lose updates.
- Minor: narrow the startup and post-update purge exception handlers from
  bare Exception to (OSError, RuntimeError).

Adds regression tests for empty-id, traversal-id, and invalid-record cases.
